1 Overview
This liaison seeks IETF SIP WG for the opinion on the XCAP Diff
Event Package as drafted in draft-urpalainen-sip-xcap-diff-event-00.
2 Proposal
OMA PAG WG deals with a requirement to enable subscription for
notification of changes in XCAP resource not only to single
document but also to single XCAP component (XML element or attribute).
This can not be achieved using draft-ietf-sip-xcap-config because the
subscription in this case is allowed only to single document or
folder.
A new SIP event package â€œxcap-diffâ€? is defined in
draft-urpalainen-sip-xcap-diff-event-00.
This event package allows subscription to a set of XCAP
resources where resources can be either folder or document
or component identified by node selector.
As this functionality fits to current requirements, OMA PAG WG
is considering adopting draft-urpalainen-sip-xcap-diff-event-00
as the solution for XCAP clients to receive partial changes of
the XCAP resources.
3 Requested Action(s)
OMA PAG WG kindly requests IETF SIP WG on the opinion on the
XCAP Diff Event Package as drafted in
draft-urpalainen-sip-xcap-diff-event-00 and its expected
progress.
4 Conclusion
OMA PAG WG would like to thank IETF SIP WG for their kind
consideration and response to this liaison request and look
forward to future opportunities to work together.
